Vertical drilling begins at Silkyara tunnel
Drilling to create a vertical escape route for the 41 workers trapped inside the collapsed tunnel in Silkyara here for two weeks began on Sunday, an official said, a day after an auger machine carrying out horizontal drilling broke down.
“Vertical drilling has begun and (a stretch of) up to 15 metres has been drilled already,” NHIDCL MD Mahmood Ahmed told reporters in Silkyara.
If it does not face any hurdle, it will take nearly 100 hours to reach the trapped workers from the top of the hill above the tunnel.
